Contained within the 3rd Edition (1957) of the Atlas of Canada is a plate consisting of six condensed maps which show the principle religious denominations of the people living in Canada. The 1951 Census of Canada enumerated the religious denomination of which each person was either a member or to which he or she adhered or favoured. This plate shows the distribution of population on this basis of the six religious groups which were most numerous in 1951. These six groups are as follows: Roman Catholic, The United Church of Canada, The Anglican Church of Canada, Presbyterians, Baptists and Lutherans. Each map is accompanied by a pie chart showing the percentage distribution of each denomination by province and territory.
